Neurology:帕金森患者中缰核和杏仁核功能失调

2017-05-12 zhangfan MedSci原创

奖赏回路的关键节点之间连通性的障碍可能是经典帕金森病态模式的主要因素,该研究对帕金森患者的分类及治疗提供新的思路

近日研究人员对缰核和杏仁核功能失调对帕金森病(PD)的影响开展了研究。

研究人员对22名典型帕金森病态患者,30名没有任何冲动的强迫行为(ICB)疾病,运动和认知状态障碍非典型帕金森病患者以及30名健康志愿者进行结构和静息态功能磁共振成像,评估缰核和杏仁核的静息状态功能并同时评估缰核、杏仁核体积和皮质厚度对疾病的影响。

研究发现,相比于健康人和PD非 ICB患者,帕金森病态患者缰核、杏仁核和丘脑和纹状体双侧功能性连接增强,双边缰核、左额叶、中央前回皮质之间的连接减少。相比于PD非 ICB患者,帕金森病态患者右侧杏仁核与海马的连接功能降低。各组之间缰核、杏仁核体积无差异;较健康人群,帕金森病态患者左额叶、中央前回、右侧颞中回和扣带回峡皮质变薄;右额下回皮质厚度较健康人群以及PD-非 ICB患者变薄。

研究表明,奖赏回路的关键节点之间连通性的障碍可能是经典帕金森病态模式的主要因素,该研究对帕金森患者的分类及治疗提供新的思路。
